iMPROVEMENT IN MACHINES FOR DRYING WOOL, 86C- Specification forming partof Letters Patent No. 34,864, dated April 1, 1862.

To aZZ whom it may concern:

Be itknown that I, JOHN PETRIE, J11, of Rochdale, in the county ofLancaster, England, have invented Improvements in Machinery or Apparatusfor Drying W'ool or other Fibrous Substances; and I do hereby declarethat the following is a full and exact description thereof.

The nature of my invention consists in the peculiar construction andarrangement of the case, air-chamber, fan, and inclined perforated orWoven-wire flaps to receive the wool to be dried, said flaps being soarranged as to expose the Wool on an extended surface to theimmediately-surrounding air, to facilitate its placement, drying, andremoval, as will be explained in connection with the accompanyingdrawings.

The drawings Nos. 1 and 2 represent the apparatus in vertical section,and the length of the same may be varied according to 'cir-' cumstances.

In the aforesaid sectional views, a Ct represent two of a series of ironbars, there being a repetition of the same at suitable intervalsthroughout the length of the apparatus. These bars are secured at top toa ridgepiece I) and at bottom to a longitudinal framing 0.

The ends of the apparatus are closed by metal or wood work I, afiixed tothe frame 0, and the bottom by sheet-iron m. At one end of the box thereis an opening it left for the passage of'air to the fan. At the otherend of the chamber thus formed is a pipe 6, leading from asteam-generator to another pipe f,

- from which several other pipes g extend in a longitudinal direction.To the framing c are fixed hinges, to which are jointed a series offlaps h, of perforated metal, Wire-gauze, or other suitable material,adapted in width of suitable size for being turned over, or a flap inone piece may be adapted, if preferred.

H II are the bearings for a shaft 1', upon which is mounted a fan L, towhich rotary motion is communicated by any suitable means.

The supports for the steam-pipes are not shown in the drawings, but theymay be carried by the framework, or by any other con venient means.

The wool to be dried is placed upon the perforated flaps h, and theshaft '0' is then put in motion, by which means air entering through theopening or will be propelled over the steam-pipes g, and from thencethrough the perforated flaps h and the wool thereon. WVhen the wool orother material is su iiiciently dried, the flags may be turned over bythe ring it, so as to deposit it upon the floor, or into any receptacleplaced there. The steam-pipesg are drawn into one at the other end ofthe machine, at which situation I apply any ordinary apparatus forallowing the water of condensation to pass oflf; but another mode ofdrying wool, which I have found to answer equally well, is shown in Fig.3, and in which case I dispense with the steam-pipes and use air at theordinary temperature, which leaves the wool in a better state forworking. i

Fig. 3 shows the apparatus in longitudinal section. A is a box orchamber, the sides of which are composed of iron, wood, or othersuitable material, covered on the top with perforated metal, wire-gauze,or other suitable material B, upon which the wool or other substance tobe dried is placed. A hole or aperture is made in the end of the box atC, through which the air is drawn by means of an exhausting-fan D orother suitable means, a current of air being thus forced downwardthrough the wool and drying it by the operation.

I may here mention that I prefer to divide the box A into two partslongitudinally for convenience, but this does not effect the principlein any way.

I am aware that airhas been driven through an inclosed chamber for thepurpose of drying material placed therein. This I do not claim; but

Vhat I do claim, and desire to secure by Letters Patent, is

The construction and arrangement of the case, air-chamber, fan, andinclined perforated or woven-wire flaps to receive the wool to be dried,said flaps being so arranged as to J r., have hereunto set myhand this26th day of August, 1861.
